The nurse is reviewing the diagnostic laboratory results for a client. The body needs all electrolytes and more for normal functioning of nerves and muscles, developing body cells, blood clotting, and coordinating all body activities.
 
  Based on this information, what is the major ion of the intracellular fluid that is responsible for the normal functioning of neurons and muscles cells, including the heart, that the nurse needs to review on the diagnostic test results? A) Sodium
  B) Potassium
  C) Calcium
  D) Magnesium

Question 2

Specific properties of water make it important in body chemistry. It is important that the student nurse is able to identify the functions of water to aid in understanding the rationales underlying nursing interventions.
 
  What are the functions of water that the student nurse needs to review for the upcoming unit examination on fluid and electrolyte imbalances?
  1 . A small temperature difference is needed to cause a physical change in water, which is normally liquid.
  2 . Water directly and indirectly participates in all chemical reactions in the body.
  3 . Water is a good solute.
  4 . Water functions as a suspension agent.
  5 . Water exerts pressure against the walls or vessels that contain ithydrostatic pressure.
  A) 1, 2, 3
  B) 1, 2, 5
  C) 2, 4, 5
  D) 3, 4, 5

Answer to Question 1

B
Feedback:
Potassium is the major ion in the intracellular fluid that maintains normal functioning of neurons and muscle cells, including the heart. Sodium is the major ion of the extracellular fluid that assists with normal functioning of neurons and muscle cells. Calcium and magnesium assists with normal functioning of neurons and muscle cells, including the heart.

Answer to Question 2

C
Feedback:
Water directly and indirectly participates in all chemical reactions in the body. Water functions as a suspension agent. Water exerts pressure against the walls or vessels that contain ithydrostatic pressure. A great temperature difference is needed to cause a physical change in water, which is normally liquid. Water is a good solvent.
